The image set created on 5 August 2003 by CHRIS/PROBA is analyzed to assess the feasibility of producing suspended particulate matter (SPM) and chlorophyll (CHL) maps. To produce these maps images are first destriped, atmospherically corrected and georeferenced. Once the data processing is finished, the results are compared with seaborne measurements and data products retrieved from other ocean...

This paper describes a fast approach to automatic point label de-confliction on interactive maps. The general Map Labeling problem is NP-hard and has been the subject of much study for decades. Computerized maps have introduced interactive zooming and panning which has intensified the problem. Providing dynamic labels for such maps typically requires a timeconsuming pre-processing phase. In the...

Saliency regions attract more human’s attention than other regions in an image. Low- level and high-level features are utilized in saliency region detection. Low-level features contain primitive information such as color or texture while high-level features usually consider visual systems. Recently, some salient region detection methods have been proposed based on only low-level features or hig...

Tactile maps are the standard media to convey geographical information to blind people. An approach for an interactive substitute for tactile maps is presented, called virtual tactile maps. It is based on an image processing system tracking fingers and game piece-like objects. Output is done through speech and sound. Users learn routes by constructing them with route bricks.

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...
